Billed as the lightest tourbillon split-second chronograph ever developed, the RM 50-03 weighs just 38 grams, strap included.
The thief, thought to be in his 30s, shoved an Azerbaijan tourist, aged 22, and stole the Formula One inspired wristwatch in broad daylight.
Police say the watch is worth €1.2 million (NZ$2 million). Only 75 of the watches exist in the world.
What's so special about them? The watch is a tourbillon - a specific mechanism of watchmaking - that means the entire mechanism inside the case rotates at a rate of one revolution per minute in order to nullify the effects of gravity.
